I have an older 90's era cnc mill I'm converting to Acorn control and I want to replace the power supply with one that I know works. My current power supply kinda looks like a fire hazard and one of its capacitors is very loose and wobbling around, I don't feel like I should trust plugging it in. My problem is, that there is no identifiable information anywhere on the power supply aside from the manufacturer that has long since went out of business. Same situation with my spindle drive servo motor, manufacturer is out of business as well.

How can I determine what power source to use? The big spindle driver servo is a 30lb/in continuous torque motor with 15.83 continuous amps if that helps identify anything.
